Gaster AU Oneshots 2

Dadster x Adopted! Child! Wolf! Reader

"I told you it was a bad idea Sans!" You whimpered as your tail was tucked between your legs. "I'll be in my room, it's starting to stop hurting. Don't tell dad." Sans said before hurrying upstairs. You hugged yourself as tears rimmed your eyes.

You had a bad feeling...

You took in a breath before wiping your eyes and sitting on the couch. You decided to read until you fell asleep. You felt the book drop out of your paws as you turned over on your side. After hours, you felt someone gently shaking you.

"(Y/n)... wake up."

"Wake up (sista/bratha)!"

Your ears perked then lowered before you slowly sat up. You saw Gaster, the skeleton who adopted you, and Papyrus, your little brother, smiling at you. "Afternoon (sweet heart/buddy)!" Gaster said as you waved. "Where's Sans?" You flinched as you looked away.

"I.. um... I can't tell you." You said nervously. Gaster gave you a confused look as Papyrus looked at him. Gaster could tell you were under pressure and even scared. "Well, if you can't tell me, could you tell," you squeaked when Gaster poked your side, "someone else?" You started to giggle nervously.

"N-nohohoo! Dad!" You squeaked before Gaster spidered your side with one hand and held your wrists in his others. "Can I help papa?" Papyrus asked as you kicked your feet and squealed. "You can tell me when (y/n) needs a break." Gaster said before he started to spider his fingers up your stomach.

"DAHAHAHAHAD! N-NO! HEHEHEHAHAHAHA!" You squealed before Papyrus lifted his hands up. "Thats enough papa!" Papyrus said before Gaster let you go. You panted as your tail wagged. "Now can you tell me?" Gaster asked. Expecting to see you smiling, he saw tears in your eyes and a shaking frown as you pointed to Sans's room.

Gaster raced up before Papyrus saw you curl up. "Is (sista/bratha) ok?" Papyrus asked as he climbed up and hugged you. "I..I'm scared Papy... I..I..I don't want Sans m..m..mad at me!" You whimpered, not knowing Gaster heard you, before Papyrus kissed your nose.

"It'll be ok! I just know it!" You smiled sadly before hugging Papyrus. Then you both heard Sans yell out in pain. You lifted Papyrus up and walked up to Sans's room. Your eyes widened to Gaster healing Sans's arm.

~ Time Skip ~

Papyrus fell asleep and you, Sans, and Gaster were up. You had tear soaked cheeks as your ears perked. "Sans, you should apologize to (y/n). (She/He) was terrified and worried." Gaster said. Sans looked at you as your sad eyes told everything. "Im sorry (y/n)..."

You smiled before gently hugging Sans. "Was that good dad?" Sans asked as Gaster joined you, Sans, and Papyrus in the bed. "Yes. But you are so grounded." Gaster said as you all fell asleep.
